Urban Green Energy Inc has installed 120 solar and wind-powered streetlights in PingQuan, situated in the Hebei province of China. Instead of opting for costly traditional lights that would have needed to sink wires into the ground and connect to the grid, the city chose a more sustainable route. Each Sanya light is equipped with a HoYi! wind turbine and two 280 watt solar panels, allowing them to function completely off-grid.
